书籍 Phase-Locked+Loops+for+Wireless+Communications
This book is intended for the graduate or advanced undergraduate
engineer. The primary motivation for developing the text was to present a
complete tutorial of phase-locked loops with a consistent notation. I believe
this is critical for the practicing engineer who uses the text as a self-study
guid ...
行业应用文档 MC145170在基本HF和VHF振荡器中的应用电路
Phase–locked loop (PLL) frequency synthesizers are commonlyfound in communication gear today. Th
模拟电子 寄存器和环路滤波器的设计
The MAX2870 ultra-wideband phase-locked loop (PLL) and voltagecontrol oscillator (VCO) can operate in both integer-N and fractional-Nmodes, similar to the Analog Devices ADF4350 wideband synthesizer.This application note compares the MAX2870 and ADF4350 registers andloop filter design in detail. U ...
模拟电子 ISM射频产品的晶体频率计算
Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate areference for the phase-locked loop (PLL)-based local oscillator (LO). This tutorial provides a basic description of theISM-RF Crystal Calculator, which can be used to calcula ...
模拟电子 XAPP854-数字锁相环(DPLL)参考设计
Many applications require a clock signal to be synchronous, phase-locked, or derived fromanother signal, such as a data signal or another clock. This type of clock circuit is important in
模拟电子 模拟cmos集成电路设计(design of analog
模拟集成电路的设计与其说是一门技术，还不如说是一门艺术。它比数字集成电路设计需要更严格的分析和更丰富的直觉。严谨坚实的理论无疑是严格分析能力的基石，而设计者的实践经验无疑是诞生丰富直觉的源泉。这也正足初学者对学习模拟集成电路设计感到困惑并难以驾驭的根本原因。.美国加州大学洛杉机分校(UCLA)Razavi教授凭 ...
电源技术 开关稳压器的偏置低噪声变容
 
Telecommunication, satellite links and set-top boxes allrequire tuning a high frequency oscillator. The actualtuning element is a varactor diode, a 2-terminal device thatchanges capacitance as a function of reverse bias voltage.1 The oscillator is part of a frequency synthesizingloop, as ...
嵌入式综合 ARM系列处理器体系结构与指令系统详解
 
常用的嵌入式处理器有ARM、MIPS、PowerPC、X86、68K/Cold fire等，MIPS是Microprocessor without Inter-locked Pipeline Stages的缩写，是由MIPS技术公司开发的一种处理器内核标准。目前有32位和64位MIPS芯片。PowerPC是早期Motorola公司和IBM公司联合为Apple公司的MAC机开发的CPU芯片，商标权同时属于IBM和 ...

方法一：(有光标闪烁，输入、删除等操作无效)
Text1.Locked = True
方法二：(无光标闪烁，不能输入、删除，界面变色、文字反白)
Text1.Enabled = False
方法三：(有光标闪烁，可删除，不能输入)
此法用两个API函数，略为复杂些。请在标准工程添加两个按钮和一个文本框： ...
VHDL/FPGA/Verilog DDR SDRAM控制器的VHDL源代码
DDR SDRAM控制器的VHDL源代码，含详细设计文档。
The DDR, DCM, and SelectI/O&#8482 features in the Virtex&#8482 -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Dig ...
